Electrical conductivity transmitter with an inductive probe
TRANSMITTERS Alphée 3100/3200
INDUCTIVE PROBES Alphée
3120/3220
- Measurement of uncompensated of a liquid using the inductive effect.
- Measurement of liquid temperature using a PT100 incorporated into the probe.
- The transmitter can be switched to standby by an external control signal (for low current drain).
- 2 measurement ranges :
- 0 - 7 ms/cm
- 0 - 420 ms/sm
- Can be used with series 2000 data acquisition units.
- Housed in a steel box for mounting on a DIN rail or in a plastic enclosure for wall mounting.
- The probe is moulded with sensitive components which are not in contact with the liquid; this gives maximum strength and reduced clogging.
- Resists chemical attack.
